Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe manufacturing technology, and in particular relates to a spraying device for spraying and wrapping thermal insulation pipes. Background Technology

[0002] Spray coating and winding technology is a production process for insulated pipes. The spray coating and winding process can determine the appropriate insulation layer thickness according to the temperature of the medium being transported in each project. After the PE layer is wound, the insulated pipe needs a rapid cooling process, which requires the use of a spray cooling device. The current spray device is an arc-shaped structure that sprays water from the upper end of the insulated pipe. The nozzle position is fixed. When the distance between the nozzle and the insulated pipe is too close, the water flow can easily cause local pits on the surface of the insulated pipe. When the distance is too far, the spray effect can not cover the surface of the insulated pipe, resulting in poor cooling effect. Utility Model Content
